Anyone??

Just got back from plymouth to yarmouth. On dash trick looking at the temp. At 70 the temp is between 105-109. Push to 80 hits the high red temp saying 124. Plant throttle count to 5 temp drops to. 115-116 for bit then rises again. Drop speed sits bout 105-108 same as round town.

Changed pressure xap. Heaters not pumping hot air just luke warm. Water bubbling like mad with air. Not convinced on head gasket as not loosing any water and she still goes like shit of shovel with no rough idle or anything associated with leaking head. Wondering if pump is failed
